Ajax call doesn't hit ASPX Page Method

Ajax call doesn't hit ASPX Page Method

Trying to call a WebMethod on an ASPX page from jQuery.Ajax call on client.  Have seen this done on several web pages and instructionals.  Problem seems to be that the actual web method is never 'hit' although the ajax call returns success, all that is in the data returned is the html of the page that made the call.

Using VS2010, jQuery 1.8.1

PAGE CODE:
  2. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebMethodReturnsDataTableJSON.WebForm1" %>

  9.     <script>

  11.         function Button1_onclick() 
  12.         {
  13.             var returnedJson = "";
  14.             //$.getJSON("WebForm1.aspx/GetDataTable",returnedJson,ReturnedJson);
  15.             $.ajax({
  16.                 type: 'POST',
  17.                 url: 'WebForm1.aspx/GetDataTable',
  18.                 data:'{}',
  19.                 datatype: 'json',
  20.                 error: (function (jqXRSMStruct,status,htmlmessage) {alert (htmlmessage) }),
  21.                 success: (function(response){alert ("success")})
  22.                         });
  23.         };

  25.         function ReturnedJson(data, textStatus, jqXHR) 
  26.         {
